We're not using Java, but rather C++. Nonetheless, the blocking is in a thread that simply reads from the UDP socket (recvfrom() call) using a blocking socket (one not marked as FIONBIO via ioctl()). No synchronization is needed because the thread gives up the CPU when there is no data to be read and the main robot code continues as normal.

HTH,
